What is wrong with my implementation / build of Farseer Physics in that I can't call certain classes?

有什么问题我先知的实现/构建物理，我不能叫某些类?。

From this map you may dispatch members of the Earthen Ring throughout the Broken Isles. Lead us to victory, Farseer!

从这张地图你可以调动破碎群岛上各个地图的大地之环成员，带领大家走向胜利！ ！

This Astral Portal will return you to Dalaran whenever you wish, Farseer. I will keep it open so that you may return here any time.

这个星界传送门可以将你传送到达拉然，我会一直打开它，你可以随时回来。

That alone would probably get The Farseer on my list as I'm a pretty big zombiephile, but the writing and story here are both top notch.

仅此一条就能让《刺客》上榜，因为我就是个僵尸爱好者（- -），但同时，此部作品的文字和故事也都是顶级的。
